Chapter 688, research and development base

Under the guidance of this commander, Yu Tian smoothly arrived at Dr. Lothar’s office.

The two fully armed mercenaries standing at the door looked at the commander and Yu Tian behind him with puzzlement.

One of them stepped forward and asked, “Commander Michael, shouldn’t you have left this place? Why Are You Back? Who Is this person behind you?”

The commander looked especially nervous because the person behind him was the most powerful person in the world, Yu Tian.

If he said this name, the two mercenaries would probably be scared to death on the spot.

There was another possibility, which was that they would raise their weapons and shoot without restraint, and they would also let more mercenaries come here.

At that time, he would also be attacked together with Yu Tian. Yu Tian was not afraid of anything. He was a demon that could not be killed.

However, he could not do it. He did not even wear a bulletproof vest.
